This paper presents the target tracking technology applied to the fire control system (FCS) which is used on warships. This FCS has the capability to track the targets moving in both high-speed-high-maneuver and low or non-maneuver motions with hybrid uncertainties. Here uses the variable structure interacting multiple model (VSIMM) algorithm as the core tracking algorithm because of its broad adaptability of target tracking. In VSIMM, the model-set is made adaptive by switching among a number of predetermined groups of models, and more cost-effective than fixed-structure IMM (FSIMM) estimator. The important applications of VSIMM estimator include the model-group adaptation logic and model-group design. This paper chose Kalman filter as the sub-filter of VSIMM algorithm. At last, this paper will present an activation-only VSIMM estimator as the simplified form of VSIMM.
